l-lAlVlE-'TUG ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 271,260, dated January30, 1883.

Application filed July 17, 1882. (No model.)

To all whom it may concern Be it known that I, ISAAC W. NUMAN, a citizenof the United States, residing at Ganton,in*the county of Stark andState of Ohio, have invented certain new and usefulImprovements inHams-Tug Attachment and Adjusting Device, of which the following is aspeciicaton, reference being had therein to the accompanying drawings.

Figure l is an outside view of one of my improved tugattachments. Fig. 2is a perspective view ot' the casing andthe metal strengthening-strips.Fig. 3 is a perspective view ofthe last said parts in the positionsoccupied when put together. Fig. 4 is a section on line .e nu, Fig. l.Figs. 5, 6, and 7 are perspectives of details. Figs. 8 and 9 are outsideviews of slightly-modied forms. Fig. l0 is a section on line y y, Fig.9. Fig. 11 is an enlarged view of a part of Fig. 10.

This invention relates to improvements in adjustable hame-tugs ol' thekind represented broadly in my Patent No. 254,683, dated March 7,1882.In said patent I showed and described a tugadjusting device consistingofa skeleton metal iramehaving a screw-rod mounted therein for movingthe end of the tug forward and back; but I have foundthat for somepurposes an adjusting mechanismof the character set forth in said patentis of an inferior nature, especially where frequent adjustment isrequired, and where the adjustmcntmust be over comparatively long`distances, inasmuch as the threaded rod must be rotated a considerablenumber of times to produce the requisite movement. Moreover, theskeleton-frame shown in said patent I find to he more expensive andheavier than i's desirable for some kinds of harness.

This invention relates toa tug attachment and adjusting device having aninclosing-case which, while being lighter than the skeletonframe andless expensive, is nevertheless as strong, and is adapted to permit theforward end ofthe tug to move with more freedom than when a" frame isused ot' the character shown in said patent.

To this end the invention consists in form ing a hollow case havingcontinuous Walls on all sides, so as to-forin a chamher,\vitl1in whichthe forward end of the tug is received and confor this purpose.

cealed. As the casing is made continuous on all sides, it may be made ofmuch lighter and cheaper material than when a solid, heavy skeletonmetal frame is employed.

The invention relates, further, to a mechanism for speedily and readilyadjusting the tug, and relates, also, to various matters which will befully described and set forth in detail hereinafter.

In the drawingsI have shown my invention as appliedv to a hams-tug inseveral modified ways, though it will he readily understood, after anexamina-tion ofthe drawings and the following description, that inmatters of detail the device may be varied without departing essentiallyfrom the invention.

The supportingand concealing casing is represented by A. This is madewith continuous walls on all sides, so as to form a hollow chamber. Asthe material of which it is composed extends continuously all around,`itmay be made of a light material, such as tin or other thin metal orwood, and I have found that papier-1nach even -may be used successfullyThis is covered with leather, which is arranged to form a tight jacketaround it, the leather being kept in form and shape by the casingwithin. The casing provides an open chamber, within which the forwardend of the tug can move freely, there being none ofthe cramping orbinding that is experienced when the end ot' the tngis compressedtightly between iiexible parts. At the forward end the tug is providedwith an eye, O, for fastening it to the haines. This eye is secured inplace in the casing by means ot' one or more screws or rivets passingthrough from one side of the casing to the other, as shown at c. Thesupporting part C of the eye-piece has an inner stem or shank, C2, whichis seated within the end of the casing to support the edges at the end,and has also an expanded part, c', which may be made ornamental forproviding a strong closing-piece and cover for the edges an d end ot'the casing. Y

The tug is represented by D. Itis provided with a series ofperforations, cl d, near its forward end. Said end is adapted to slidein and out of the casing A at the rear open end. Then the length of thetug is to loe changed it is moved in or out far enough to bring the IOOproper aperture d opposite to the apertures a u', which are formed inthe side of the casing A. Through these apertures there passes a pin, E,adapted to go through the tug. The pin is prevented from seriouslywearing or straining the casing or the leather covering thereof by meansof an eyelet, E', fastened in the aperture a and an eyelet, E2, in theaperture a'. With thev pin there is combined a locking device adapted toprevent its being accidentally withdrawn. I prefer is shown in thedrawings at F, it consisting of a sliding bolt seated beneath the plateE3, which latter is preferably formed in one pi'ece with the eyelet orpart E2.

Having thus described what I consider the essential features of myinvention, I will now set forth the devices which may be combinedtherewith' to make a still more advantageous tug attachment andadjusting mechanism. Thus the hollow light casing may be strengthened bymeans of two strips, G G, of steel, opposedto each other-that is, placedupon opposite sides of the casing and secured thereto by rivets. Whenthe lcasing (strong enough ot' itself under ordinary circumstances byhaving the walls continuous) is supplemented by these metal strips thereis produced a very durable tug attachment, capable of withstanding themost serious strain and wear. Again, l prefer to attach the pin E to adat metal spring, H, so that it shall automatically pass through theapertures and tend to, be held by the spring in place. I is a leathercover, situated behind the spring H, to form a facing or jacket for it,so that the horse shall not be affected by the metal ofthe spring. Theleather preferably extends beyond the spring, as shown at t', to form aconvenient flexible handle to pull the spring back.

ln Fig. 7 I have shown an improved form of a loop or buckle to becombined with the easing and the tug. 1t is constructed in two parts,one consisting of the back plate, J, the upper loop, J', the lower loop,J2, the end loop, J2, and the arms J4 J4, provided with rivetpieces j j,andthe other part consisting of a cross-bar, J 5, provided withperforations at the ends adapted to tit upon and be riveted against thearms J 4.

Atj j the back plate is riveted to the inner hollow casing, A. It is cutaway or provided with a recess, J6, which permits the pin E to bereadily inserted and withdrawn, and also allows the spring H to lieclose to the casing.

Heretofore the loops or buckles corresponding to those just describedhave been secured to the leather parts by means of stitching; but forheavy harness I tind this method of riveting the loop or buckle to theattachment casing to be much better. The cross-barJ5 of this loop orbuckle may be perforated at the center, so that the central part thereofshall act as the eyelet E2. With it also may be formed integrally theplate E3, beneath which lies the lock F. This latter is preferably madeThe form oflock which of awire or rod bent to have theoutwardly-projecting partf, (in the slotf-,) by which it can be movedback and forth. There is a groove in the under side of the plate, whichoperates as a guide for the lock. The pin E is provided with anaperture, into which the lock passes, though a slot may be used insteadof the aperture, if desired.

In Fig. l() I have shown the tug attachment in the form in which Iprefer to make it for use with breast-collars. The manner of securing itto the collar-will be readily understood.

It will be seen that the hollow casing A provides a strong support forthe eye-piece G for the spring which carries the locking-hinge and forthe loops at the rear end, all of which are formed separatelylfrom thecasing and riveted or otherwise secured thereto. The casing insures thatall of the parts of the tug attachment shall be held constantly insubstantially the same position relatively to each other, and istherefore much better than the casing devices which have been made ofleather, and therefore liable to stretch so as to vary the positions ofthe parts.

What I claim isl. The herein-described tug attachment, consisting of theeye-piece (.l, the pin E, which fastens the tug and is'held in placeindependently of the tug, and the devices for preventing accidentalwithdrawal of the pin from the tug, in combination with the hollowcasing A, having continuous walls on allsides, and formed separatelyfrom said eye-piece C and pin E, and connected, substantially as setforth, to thedevices which hold pin E,wherebystrain ing of the leatherparts is prevented and a concealing-chamber is provided for the forwardend of the tug.

2. The combination, with the hollow casing A, of the tug provided with aseries of perforations at its end, the pin E, the perforated plates oreyelets E' E2 in the walls of the cas'- ing A, and means for preventingthe withdrawal of said pin, substantially as set forth'.

3. The combination, with the casing, the haine-tug provided withperforations, and the pin adapted to pass through the perforations, ofthe spring permanently secured to said pin, substantially as set forth.l

4. The combination of the casing, the tug provided with perforations,and the pin E with the spring and the leather covering for said spring,extended beyond the end thereof to form a iiexible handle, substantiallyas set forth.

5. The combination of the hollow casing having continuous walls on allsides, the eye C, formed separately from and rigidly secured to saidcasing, the pin E, passing through the rear end of the casing from oneside to the other, the lock F, the plate E2, secured to one side of thecasing, and the devices which prevent accidental withdrawal of the pin Eafter it is unlocked, secured to the casing on the side opposite to thelock, substantially as set forth.
